A space time of 3 hours for a flow reactor means that
the time required to process one reactor volume of feed (measured at specified conditions) is 3 hours.
three reactor volumes of feed can be processed every hour.
it takes three hours to dump the entire volume of the reactor with feed.
conversion is cent per cent after three hours.
